CJ2102A

Changjing · MOSFETs · SOT-323

CJ2102A from Changjing, in a SOT-323. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GATE input Gate terminal of the N-channel MOSFET; the gate-source voltage is rated at ±8 V (VGS), with a gate threshold of 0.65 to 1.2 V.
2 SOURCE passive Source terminal of the MOSFET; the continuous source-drain diode conduction current IS is rated at 0.6 A.
3 DRAIN passive Drain terminal of the MOSFET; the drain-source voltage is rated at 20 V (VDS) with a continuous drain current ID of 2.1 A.

CAD (KiCad official)

  • Symbol: CJ2102A
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: cj2102a-etched.step / cj2102a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj2102a.step / cj2102a.glb are the bare package body.
